Answer:
8. When cells are placed into a hypertonic solution, water will tend to move out of the cells and into the surrounding solution. This can cause the cells to shrink, a phenomenon known as crenation. In contrast, if cells are placed into a hypotonic solution, water will tend to move into the cells, causing them to swell and potentially burst.
9. Turgor pressure is the pressure exerted by the contents of a cell against the cell wall. In plant cells, turgor pressure is important for maintaining the shape and rigidity of the plant. When a plant is placed in a hypertonic environment, the loss of water from the cells can reduce turgor pressure and cause the plant to wilt or droop. This can make the plant less able to support itself and may affect its ability to grow and function properly.
